Application May 3, 1957, Serial No. 656,836 I 4 Claims. (Cl. 139-391) This invention relates to pile fabric and more particularly to floor coverings of the loop pile type which are made on looms having pile forming wires.

An object is to produce a loop pile floor covering of the above type having a novel and improved appear- 311C6- Another object is to produce a loop pile fabric in which a random pattern effect is obtained.

Another object is to produce a loop pile fabric having pile loops of contrasting effects which are randomly disposed over the surface of the fabric.

Another object is to provide a simple and efficient method of fabricating such a fabric by weaving, knitting, tufting or hooking procedures.

Various other objects and advantages will be apparent as the nature of the invention is more fully disclosed.

In accordance with the present invention, the pile warps are woven in pairs consisting of contrasting yarns which are fed through the same reed dent.

The pair of warp yarns is passed over a pile forming wire to form a pair of adjacent or contacting pile loops. Fillerwise a plurality of such pairs of loops are closely spaced to form a group, the groups being spaced apart a greater distance than the pairs within each group.

As a specific example, two pairs of loops may be woven in adjacent dents to lie contiguous to each other in a group with two pairs of ground chain warps between adjacent groups. The groups may be staggered in successive rows in a basket weave if desired.

During the weaving no attempt is made to control the relative positions of the loops of each pair. Hence their order in a fillerwise direction becomes randomly reversed and in some instances one of the loops is masked or partly masked by the other. When the two loops of each pair are composed of contrasting yarns a random pebbly effect is produced.

The nature of the invention will be better understood from the following detailed description taken in connection with the accompanying drawing in which a specific embodiment has been shown for purposes of illustration.

In the drawing:

Fig. 1 is a diagrammatic view the invention;

Fig. 2 is a warpwise section of the fabric showing the different arrangements of the loops of the various pairs;

Fig. 3 is a fillerwise section taken on the line 33 of Fig. 2; and

Fig. 4 is a plan view of a fabric illustrating the random pattern effect.

Referring to the drawing more in detail the fabric is shown as comprised of pile loops of one type or color of yarn and pile loops 11 of a contrasting type of color. The loops 10 and 11 are woven together as adjacent loops of a pair.

A single fillerwise row consists of two pairs of loops 10 and 11 which are closely spaced, followed by two pairs of chain warps 12 forming the ground. The sequence is repeated along the entire row. The pile warps of a fabric embodying and chain warps are bound by filler shots 13 in the usual manner to form a woven backing.

Adjacent. pairs of loops 10 and 11 which form a group may be separated by chain warps if desired provided the spacing between pairs in each group is maintained less than the spacing between groups of pairs. Also the number of pairs in each group may be varied.

In Fig. 2 the pile loops are shown as bound under alternate filler yarns 13. It is to be understood that other pile loops may be staggered and bound under alternate filler shots as in the usual basket weave.

In the above fabric the order of the loops 10 and 11 random design in the finished product.

The fabric may be woven on a stationary wire loom of the type shown in the Faber Patent No. 2,355,789, dated August 15, 1944, and in the Bloch Patent No. 2,497,716, dated February 14, 1950, which include stationary warpwise pile forming wires and a leno motion to lay the pile warp across the wires from alternate sides.

The two Warp yarns of each pair are fed through the same reed dent and are handled as a single warp by the leno mechanism. Hence they may lie in regular or reversed order over the Wire. This random arrangement is enhanced by the grouping of adjacent pairs of loops :as above described wherein either like yarns or unlike yarns of adjacent pairs may lie adjacent each other.

The fabric woven on a stationary wire loom of the above type is characterized by pile loops which in plan view extend at a slight angle to the warpwise direction. This further increases the random effect.

The fabric may also be woven on a pull-wire loom of the velvet type in which case the loops extend in a warpwise direction in plan view. The random effect of a fabric of the latter type may be less pronounced than in the case of fabric woven with a leno type mechanism as the tendency of the two warp yarns to become displaced is less with a velvet type heddle motion. The method of weaving will be selected in accordance with the result desired.

An over-all effect is illustrated in Fig. 4 wherein the various pairs of loops 10 and 11 are distributed across the face of the fabric and are varied in position in the different areas to produce a somewhat irregular striped effect as shown. It is of course understood that the number of pairs of adjacent loops in each group may be varied and the spacing of the pairs and of the groups may also be varied. Furthermore, three or more yarns of different characteristics may be fed through the same dent if desired instead of the two yarns shown in the drawings. This will further enhance the randomness of the product. A three or four color effect can be obtained by using differently colored or differently characterized yarns to form two adjacent pairs of loops, for example one pair may consist of white and gray yarns and the adjacent pair may consist of black and gray yarns. When these are randomly disposed as above described a three color effect is obtained.

It is also to be understood that the loops may be cut either by cutting wires or by shearing to produce uncut pile having the same random effect.

Obviously, the same effect may be produced in knitted, tufted or hooked fabric by arranging the feed so as to produce spaced groups of pairs of loops as above described. The effect produced in the method described above is similar to that which has heretofore been obtained only by the more expensive processes of space dyeing or ombre dyeing. However, the present arrangement is distinguishable from the space dyed products by reason of the grouping of the pile tufts.
